LCO T1-O L l� ETECTTO ITT D EN <br />y Officer Aron Sandlnann <br />Officer Matt Langreck <br />The Centennial Lakes Police Department uses two types of alcohol detection <br />devices; the hand held preliminary breath test (PBT) and the Intoxilyzer <br />5000. <br />The department uses two types of PBT's; the <br />Alco- Sensor IV and the Lifeloc. These hand <br />held devices utilize plastic mouthpieces and are <br />used to detect blood alcohol content (BAC) from <br />human breath samples. Both devices have <br />digital readouts. These devices are often utilized <br />by officers to supplement field sobriety testing <br />and to detect underage alcohol consumption. <br />The department, at the end of 2010, had six <br />Alco- Sensors and one Lifeloc. PBT's are <br />calibrated and tested on a monthly basis. <br />The Intoxilyzer 5000 is used for the detection of blood alcohol content for <br />evidentiary purposes in traffic related cases such as DWI . Officers must <br />attend a course at the BCA to become Intoxilyzer operators. <br />The Intoxilyzer tests two breath <br />samples to calculate BAC. The <br />Intoxilyzer solution is changed on a <br />monthly basis and is maintained by <br />officers with help from the BCA. <br />4 <br />f <br />t <br />1/ <br />W . <br />
